Abstract

Régulateur effectuant une intégration des modes de réglage de la poussée principal et secondaire en une unique commande redontante pour réduire la complexité du système. Il comporte un générateur 30 de signal de référence de vitesse de la soufflante et un générateur 44 de signal de référence de rapport des pressions du moteur qui produisent des signaux N1a et EPRa fonction de la poussée demandée qui sont comparés respectivement à la vitesse de la soufflante et au rapport effectif des pressions du moteur par des additionneurs 26, 40 pour produire des signaux d'erreur appliqués à un générateur 50 de paramètre de poussée qui applique au moteur 22 un signal de régulation fonction des deux signaux d'erreur dans le cas où l'un des circuits fonctionne anormalement, le générateur 50 fonctionnant alors uniquement en réponse à l'autre circuit. Application aux moteurs d'avion à réaction.Regulator integrating the main and secondary thrust adjustment modes into a single redount control to reduce system complexity. It comprises a blower speed reference signal generator 30 and an engine pressure ratio reference signal generator 44 which produce signals N1a and EPRa as a function of the requested thrust which are compared respectively to the speed of the blower. and the effective ratio of the engine pressures by adders 26, 40 to produce error signals applied to a thrust parameter generator 50 which applies to the engine 22 a regulating signal dependent on the two error signals in the case where one of the circuits operates abnormally, the generator 50 then operating only in response to the other circuit. Application to jet aircraft engines.
